# ngx-modal-ease
# Description
ngx-modal-ease is a versatile Angular library providing a lightweight, simple, and performant modal. This library supports data communication between components, opening of multiple modals, custom animations, and a range of customisable options.
Support Angular version starts at v16 (see changelog).
# Demo
Live demonstration of the ngx-modal-ease library [here](https://greenflag31.github.io/modal-library/ngx-modal-ease).
# Installation
| Version | Command | Description |
| ------- | -------------------------- | --------------------------------------------------------------------------------------------------- |
| V16 | npm i [email protected] | Install the V16 compatible version. |
| V17 | npm i [email protected] | Install the V17 compatible version. |
| V18 | npm i ngx-modal-ease | Install the V18 compatible version. This version is compatible with a zoneless Angular application. |
# Options
The modal supports a range of customisable options:
```javascript
Options {
modal?: {
enter?: string;
leave?: string;
top?: string;
left?: string;
};
overlay?: {
enter?: string;
leave?: string;
backgroundColor?: string;

| enter | | Define the enter animation for the modal or the overlay respecting the [shorthand animation property](https://developer.mozilla.org/en-US/docs/Web/CSS/animation). |
| leave | | Define the leave animation for the modal or the overlay respecting the [shorthand animation property](https://developer.mozilla.org/en-US/docs/Web/CSS/animation). |
| top | 50 | Top position of the modal in percent. Can be defined in any measure unit. |
| left | 50 | Left position of the modal in percent. Can be defined in any measure unit. |
| backgroundColor | rgba(0, 0, 0, 0.4); | Background color of the overlay. Can be defined in any color notation (rgba, hex, hsl, ...). |
| minHeight | | Minimum height of the modal. Can be defined in any measure unit. |
| height | | Height of the modal. Can be defined in any measure unit. |
| width | | Width of the modal. Can be defined in any measure unit. |
| maxWidth | 100 | Max width of the modal in percent. Can be defined in any measure unit. |
| padding | 0.5 | Padding to be applied on the modal in rem. Can be defined in any measure unit. |
| escape | true | Enable escape to close the current modal. |
| click | true | Enable click outside of the modal to close the current modal. |
| data | | Data communication between components under the form of key-value pairs. Any type of data is supported. |
# Complete Example
Inject the ModalService through regular dependency injection in your component.
In the following example, `ModalContentComponent` is the content of the modal and should be provided as first parameter. As second parameter, provide an object respecting the `Options` interface (see above).
NB: _From the V18 compatible version, observables have been transformed to regular Promises to anticipate the future optional RxJS._
```javascript
this.modalService.open(ModalContentComponent, {
modal: {
// animation
enter: 'enter-scale-down 0.1s ease-out',
},
overlay: {
// animation
leave: 'fade-out 0.3s',
},
size: {
// modal configuration
width: '400px',
},
data: {
// data to ModalContentComponent
type: 'Angular modal library',
},
})
// .then() or async / await for V18 compatible version
.subscribe((dataFromModalContentComponent) => {
...
});
```
Any type of data can be provided between components. Create the corresponding property (here, `type`) in your component (here, `ModalContentComponent`) and the property will be assigned with the provided value.
In your `ModalContentComponent`:
To pass information from the `ModalContentComponent` to your current component, inject the `ModalService` through regular dependency injection and call the `close(data)` method from the service with any data you wish to send back to your component. This method returns an RxJs subject (_a promise for V18 compatible version_), so subscribe to it as shown in the above example. It is not necessary to unsubscribe from the subscription since it will automatically `complete()` in the service.
```javascript
// Inside ModalContentComponent
onClose() {
this.modalService.close(this.dataToSendBack);
}
```
Publicly available methods have been exhaustively documented and typed, so you should get autocomplete and help from your code editor. Press on `CTRL + space` to get help on the available properties in the `Options` object.
# ModalService
This library exposes a `ModalService` that contains the following API:
```javascript
// Opens a component inside the modal
open(componentToCreate: Type, options?: Options);
// Close a modal with optional data to send back
close(data?: unknown);
// Close all opened modals
closeAll();
```
NB: Z-index of overlay and modal start at 1000 and 2000 respectively. In case of multiple modals, z-indexes will be incremented by 1000.
# Ready-to-use animations keyframes
This library comes with predefined and ready-to-use animations keyframes. Just fill in the `name`, `duration` and `easing function` (more info on the `animation CSS shorthand` [here](https://developer.mozilla.org/en-US/docs/Web/CSS/animation)). Those animations are _position agnostic_, so if you wish to position your modal at other `top` and `left` values than default, it will correctly work. Of course, you can create your own keyframes too.
```css
/* Recommended: 0.2s ease-out */
@keyframes enter-going-down {
from {
transform: translate(-50%, -60%);
}
to {
transform: translate(-50%, -50%);
}
}
/* Recommended: 0.2s linear */
@keyframes enter-scaling {
from {
transform: scale(0.8) translate(-50%, -50%);
transform-origin: left;
}
to {
transform: scale(1) translate(-50%, -50%);
transform-origin: left;
}
}
/* Recommended: 0.1s ease-out */
@keyframes enter-scale-down {
from {
transform: scale(1.5) translate(-50%, -60%);
transform-origin: left;
}
to {
transform: scale(1) translate(-50%, -50%);
transform-origin: left;
}
}
/* Recommended: 0.3s linear */
@keyframes fade-in {
from {
opacity: 0;
}
to {
opacity: 1;
}
}
/* Recommended: 0.3s linear */
@keyframes fade-out {
from {
opacity: 1;
}
to {
opacity: 0;
}
}
/* Recommended: 0.7s linear */
@keyframes bounce-in {
0% {
transform: translate(-50%, -85%);
}
18% {
transform: translate(-50%, -50%);
}
60% {
transform: translate(-50%, -65%);
}
80% {
transform: translate(-50%, -50%);
}
90% {
transform: translate(-50%, -53%);
}
100% {
transform: translate(-50%, -50%);
}
}
/* Recommended: 1s linear */
@keyframes scale-rotate {
30% {
transform: scale(1.05) translate(-50%, -50%);
transform-origin: left;
}
40%,
60% {
transform: rotate(-3deg) scale(1.05) translate(-50%, -50%);
transform-origin: left;
}
50% {
transform: rotate(3deg) scale(1.05) translate(-50%, -50%);
transform-origin: left;
}
70% {
transform: rotate(0deg) scale(1.05) translate(-50%, -50%);
transform-origin: left;
}
100% {
transform: scale(1) translate(-50%, -50%);
transform-origin: left;
}
}
```
If you create your own keyframes, I would recommend to create a new file `modal-animations` (.css or preprocessor), and @import it in your `styles.css` (or preprocessor) at the root of the application.
# SSR (Server Side Rendering)
This library supports Server Side Rendering (SSR). The modal will not instantiate during server-side execution, as it requires access to the DOM API.
# DX Friendly
This library has been documented and should provide autocomplete and help from your code editor. Tested on VS Code.
# Performance
Emphasis has been placed on performance, adopting `ChangeDetectionStrategy.OnPush` strategy. This library respects Angular's mindset and use the Angular API to create components. Modal components will be removed from the DOM after closing.
# Change log
Version 0.0.4: Fixed of a communication bug between components. Every modal has now its own subject to send back data to the calling component.
Version 0.0.5: Fixed a bug between components that prevented the component from closing when applying different animations with multiple stacked modals.
Version 0.0.6: Added V16 backward compatibility support.
Version 0.0.8: Incorporated internal component destruction to ensure proper invocation of the child's OnDestroy lifecycle hook.
Version 0.1.0: Added the V18 version. This version is compatible with a zoneless Angular application. Optional RxJS has been anticipated, observables have been transformed to regular Promises / event listeners.
